Abstract (en)
[origin: EP2008809A1] A low permeability rubber laminate containing (A) at least one pricked low permeability resin layer having, wherein the low permeability resin has an average thickness d of 0.05 µm < d< 10 µm provided with a plurality of holes (i.e., pricked holes), an air permeation coefficient determined according to JIS K7126 of 0.5×10 -12 cc·cm/cm 2 ·sec·cmHg or less and (B) at least one rubber layer, whereby the blistering of the low permeability resin layer is suppressed to achieve a superior air pressure retention performance as well as a pneumatic tire using the same.
